Abstract

The embodiment of the invention provides a locomotive electrical control system, which comprises a main circuit, a control unit and a power supply unit, wherein the main circuit comprises a first traction unit, a first braking unit, a second traction unit and a second braking unit, wherein the power supply unit is connected with the first traction unit, the first braking unit, the second tractionunit and the second braking unit, and the first traction unit is connected with the first braking unit, the second traction unit and the control unit; and the second traction unit is connected with the second braking unit. According to the locomotive electrical control system, when the first traction unit fails, the second traction unit can still drive a train to run, and thus the traction performance of a locomotive is improved, and the failure rate is effectively reduced.

Description

technical field [0001] The invention relates to the field of locomotive control, in particular to an electric control system of a locomotive. Background technique [0002] The electrical system of the locomotive is supplied with direct current by the storage battery (or supercapacitor), and the direct current is converted into three-phase alternating current with adjustable voltage and frequency by the traction inverter to drive the traction motor, and then drive the locomotive to run. [0003] In the prior art, the electric control system of the locomotive adopts the mode of one dragging two to control and pull the whole locomotive. Specifically, the electrical control system of the locomotive provides 540V DC power from the battery, which is directly supplied to a traction inverter after passing through a 630A large-scale air switch. Asynchronous traction motor. [0004] However, with the existing technology, when the traction frequency converter fails, the electrical co...
